I have always wondered about the factory umbrella covers on chevy valve springs. If I have replaced the springs on a race engine, I leave them off and have been told to by some people. I'm assuming they are just to keep oil on the outside of the spring instead of so much on the valve? We are about to work on some more and I am wondering if I really should take them off or put them back on with the new springs. I haven't had any problems with them off. Thanks!

I like to run the umbrella type seals because they will shed oil away from the valve guide but still allow enough oil on the stem and guide to keep things lubed. In the past engines that I have seen with no seals tend to smoke a little bit.

Sorry, maybe I need to explain myself a little more. It's not the valve seals, I mean the metal cup that is on top of the spring under the keeper and lock.

It's part of the retainer. Get rid of it. It's only there for stock spring cooling. You don't need it or want the extra wieght.

Thanks Lizard! I was hoping for that kind of an answer.

while your at it id get new retainers as well. No need using the stock heavy ones. I think Ive seen some decent aftermarket stock diameter retainers for under 40-50$.
